Question

a biology teacher asks students to give examples of genetic variations that support the idea that changes in populations environment affect genetic variation. which is the least supportive example?
changes in genetics in human populations
antibiotic resistance in bacteria populations
pesticide resistance in garden insects
changes in the color of the peppered moth population in england

Explanation:

• Antibiotic resistance in bacteria, pesticide resistance in insects, and peppered moth color shifts are classic, direct examples where environmental pressures (antibiotics, pesticides, industrial pollution) drive measurable, rapid genetic changes in populations.
• Changes in human population genetics are far more gradual, influenced by a complex mix of weak, multifaceted environmental and social factors, making them the least clear, direct example of environment-driven genetic variation compared to the others.

Answer:

changes in genetics in human populations
